Executive Summary
2
As large airline companies compete to reduce emissions, fuel burn, noise, and maintenance costs, it is expected that more of their
aircraft systems will shift from using turbofan propulsion, pneumatic bleed power, and hydraulic actuation, to instead using
electrical motor propulsion, generator power, and electrical actuation. This requires new flight-weight and flight-efficient
powertrain components, fault tolerant power management, and electromagnetic interference mitigation technologies. And NEAT is
the first reconfigurable hybrid gas-electric propulsion testbed capable of supporting full-scale single-aisle electrified aircraft
powertrain technology including:
High fidelity turbo-generation and ducted fan transient emulation, Establishing baseline power quality and electromagnetic interference levels, Validating aircraft powertrain modeling tools Demonstrating single-aisle flight-weight powertrains Ground test research motors and inverters under flight altitude conditions at full power levels
Reduce single-aisle aircraft carbon use,
noise and emissions in US airspace
